DUMP-CAR.

Specification of Letters Patent.

Patented Nov. 29, 1921.

Application led December 11, 1920. Serial No. 430,074.

To all whom t may ooncewb:

Be it known that I, DAVID HINDAHL, a citizen of the United States, residing at Chicago, in the county'of Cook and State of Illinois, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specication.

This invention relates to dump cars, and particularly to combination side and center dump cars.

In railway ballast work there is great advantage in dumping the ballast material at the proper polnts with respect to the rails in a manner to prevent covering the latter.

One object is to center and side dump ballast material in a simple, efficient and improved manner whereby the ballast material is properly deposited with respect to the rails and prevented fromovering the same.

Another object is to provide in a dump car means whereby the How of dumpable material to opposite sides of a rail is accurately controlled.

Another objecty is to improve generally the construction of dump cars in a manner 'to better fit same for the severe treatment which they receive.

These and other objects arel accomplished by means of the arrangement disclosed on the accompanying sheets of drawings, in which- Figure l is a fragmentary side elevation of a railway dump car embodying my invention;

Fig. 2 is a transverse sectional view of the same dump car showing the door structure arranged for center dumping;

Fig. 3 is a similar transverse sectional view of the same dump car showing the door structures arranged for side dumping;

Fig. 4 is a fragmentary plan View of the same car, some floor parts being removed for the sake of clearness; and,

Fig. 5 is a detail top plan view of the side stake securing means.

The various novel features of my inventionl will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

Referring to the figures of the drawings, it will be noted that my invention is illustrated in connection with a dump car having sides 10, ends 11 and a bottom, which in this case is a hopper bottom, there being two hoppers 12 fo-rmed on opposite sides of the center sill structure 9, the latter including downwardly extending vertical members 8 from the lower ends of which downwardly and outwardly inner stationary slopingl hopper side walls 13 extend. For overcoming the restricting effect of outei anges overhanging the sill members 8 and for increasing vthe veffective hopper dumping width, an inverted channel 7 is inserted between the upper edges of member 8. The lower ends of the downwardly yand outwardly sloping members 13 are braced by cross bracing members 13. The other walls of the hoppers 12 are composite'in construction and take the form of door structures to be referred to more particularly hereinafter, and vertically arranged frame members 6 extending longitudinally between and secured to adjacent cross frame member 6 by suitable brackets 5. AThe lower edges of these frame members 6 are turned inwardly to protect the adjacent hinges 19 tobe referred to later. The 4car shown -is of a convertible nature in that a fiat Lioor is rovided including movable members 14 which, as shown in the figures of the drawings, may take an inclined position in which they are supported by the car sides to form hopper side walls. These members 14 are movable into horizontal position to form portions of a continuous flat floor, of 'which floor members 15 form a part. The car sides 10 also include side wall doors 16, which are pivoted along their upper'edges at 17, whereby' such doors 16 may swing outwardly, with a flat floor arrangement, for dumping at least a portion of the lading to the sides of the car. In this connection attention is called to the' fact that these cars, when arranged as flat bottom cars, arel unloaded through the side doors 16 by plows which are drawn through the cars from end to end, forcing the .lading outwardly. Such unloading plows at times do considerable damage to the side stakes 30 which extend into the loading space. To support andv reinforce these stakes in an improved manner, I have provided same with channelshaped rub plates 31 which are secured to the stakes and to brackets 32 which in turn are secured to the side sills 33.

Particular reference will now be had to means whereby-the flow of dumpable material from the hoppers 12 may be accurately controlled, and more specifically to means whereby ballast material is properly deposited with respect to the rails and prevented from covering the latter. As mentioned hereinabove, the center sill yshown in Fig. 3. The opening and closing movements of the door frames are controlled by any suitable door operating mechanism including links 21 operatively connected to said door frames and to chains 22 coperating with an operating shaft 23. Pivotally mounted in each of these door frames is one or more doors 24 which preferably are pivoted in the door frame as'at 25 at avpoint just below the lower extremity of the associated inner hopper side wall13 so that when the doors 24 are in an open position, as shown in Fig. 3, the doors 24 and the inner hopper walls 13 form a continuous shedding surface which may or may not be in the same plane, in accordance with requirements. These doors 24 are controlled by any suitable door operating mechanism, including chains 26 operatively connected to the doors and to operating shafts 27. Forming a part of each of the door structuresA is a downwardlyand inwardly extending shedding plate 28 which is located within the upper half of the door frame 18, the' lower edge of which plate is spaced from the lower extremity of the associated inner hopper side wall 13 to provide a restricted dumping exit 29 whereby the control 'of the flow of the dumpable material to the vouter sides of the rails is made more efiicient.

As shown in Fig. 3, of the drawings, the door frames proper are held in closed position and the doors 24 pivotally mounted in said frames are in open position whereby dumpable material is directed to the outer sides of the rails. It will be noted that the outer edges of the doors 24 are located directly outside ofthe rails for definitely positioning the dumpable material or ballast where it is to be used and in a manner such that the ballast will not cover-the rails. With the doors 24 in the open position it will be appreciated that were the exit opening 29 not restricted by the plates 28 or equivalents thereof, the dumpable material would iow outwardly in a less controlled manner, causing such material to rush outwardly far beyond the outer edges of the rails. In this same connection it `will be appreciated that no dumpable material will be dumped to the side ofV a .car until .the doors 24 are considerably below the horizontal position and in this manner the members 28 aid in preventing an initlal rush of the dumpable material to a point far beyond the outer sides of the rails. y

It will be understood that when it is desired to center dump, the doors.24 will occupy a closed position with respect to the doorframes 18, as shown in Fig. 2. This figure shows the door structures in open position for controlling the depositing of the ballast between the rails and in a manner to prevent such ballast` from-covering the rails. The lower edges of the door frames 18 lie a considerable distance within the rails and a less distance above the same so that there is little or no possibility of any ballast material covering the rails. With the parts in the position 'lshown in Fig. 2, it will be noted that the control plates 28 do not form the restricting function as they do in connection with side dumping, these control plates forming a part of the door frame and being movable therewith. The inner hopper side walls 13, however, coperate with-the door struc-Y tures for center dumping to restrict the flow of dumpable material in a manner whereby the flow is more controlled than otherwise would be the case.

In effect, in this combination center and side dump arrangement, there is provided a door within a door, the main door comprising the whole door structure in each case, which is moved into an openposition with respect to the car, while the auxiliary doors 24 are in closed position with respect to the door frames for center dumping, as shown in Fig. 2. For side dumping, each of the door frames 18 is in closed position with respect to the car, while the auxiliary door 24, which is the door ,within a door, in each case is in an open position, as shown in Fig. 3. 1t is my intention to cover all modifications of the invention falling within the spirit and scope .of the following claims.
